Transnational drug trafficking has been effectively curbed, and running big rackets across China's borders made almost impossible, senior police officers said yesterday.

This is the first time in years that police have made such a statement, and it means law enforcement agencies have thwarted attempts to use the country as a transit point and make it a consumption market for drugs.

According to Ministry of Public Security figures, border police unearthed 265 drug-trafficking cases in the first 9 months of this year, up 40 percent year-on-year.
